The Lycée Condorcet, opened in 1803, is one of the four oldest high schools in Paris and also one of the most prestigious. During the greater part of the nineteenth century, the school was the "great Liberal High School" on the right bank with its relatively flexible regime that was chosen by the progressive bourgeoisie for its sons. It is among the few schools in Paris that never had internships: students who were not living with their parents worked, ate, and slept in the neighbourhood via a network of "maitres de pension". The mix has gradually emerged in 1924 for preparatory classes for the grandes écoles, and 1975 for secondary classes.
The facility has brought successively names: High School of the Chaussée d'Antin (1804) Imperial High School Bonaparte (1805 - 1814) Royal College of Bourbon (July 1815 - February 1848) Imperial High School Bonaparte (1848 - 1870) Lycée Condorcet (22 October 1870 - 1874) School Fontanes (1 May 1874 - 27 January 1883) Lycée Condorcet (since 1883)
Preparatory classes are also very old and were treated to famous teachers such as Jean-Paul Sartre.
